Optical Fiber Power Meter

Looking for an OPM with accuracy that won't break the bank. I'm talking $50.00 or less. Any suggestions?

Patent Application **Optical Power Reduction by Masking Pixels of Image Content**

Abstract September 9, 2021

“ A scanning laser projection system includes a virtual protective housing circuit to automatically reduce accessible emissions of visible laser light by decimating areas of a projected image to reduce optical power exposure levels for safety, comfort, aesthetic, or system classification purposes. IR laser light pulses are scanned in a field of view, and a percentage of visible laser light pulses are blanked based on attributes of reflections of the IR laser light pulses.”
